TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 408,003, dated July 30, 1889.

Application filed August 13, 1888. Serial No. 282,633. (No model.)

To all 1071/0722 it may concern:

Be it known that I, ALFRED G. FISHER, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and use ful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to temporary binders for magazines, pamphlets, and papers, the object being to provide for such articles a form of book-cover having applied thereto improved devices for temporarily or otherwise securing said articles therein; and the invention consists in the peculiar construction and arrangement of said pamphlet-securing devices in connection with a cover or other thing suitable for receiving and holding the same, all as hereinafter fully described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective view of a book-cover having my improved temporary binder devices applied thereto. Fig. 2 is a perspective view of one end of several pamphlets or series of folded sheets of paper having a portion of said devices attached thereto. Fig. 3 is a sectional view of a portion of said cover and of said binder devices on line a; m, Fig. 1, showing the latter attached to a series of folded sheets of paper or to several pamphlets within said cover.

In the drawings, A indicates a book-cover, of which 3 is the back. The said binder devices consistof a metallic base-plate 4, of sheetiron, brass, or similar material, having a lip 5 formed on the opposite edges thereof, and a wire or similar hook or binder-yoke, having two substantially parallel arms 0 c, united at one end by an intermediate curved bar (I, said bar having preferably a curvature of about one-half of a circle, substantially as shown. The said lips 5 are only so far bent over the face of the base-plate 4: as to leave a groove under each lip to receive one of the arms 0 of said binder-yoke, and the base-plate is secured to the inner side of the back 3 by riveting, as shown, or by any other suitable means. The base-plate 4c is shown in the drawings as having a length of about onehalf that of the arms 0; but that length may be varied, and any suitable hooks having substantially the form of the lips 5, under which said arms can be held, may be substituted for said plate, if desired.

The two binder-yokes usually applied to a cover, as shown in Fig. 1, may each have arms of equal or unequal length; but the latter are preferable, as shown by the yoke at the lower end of the cover A in Fig. 1, the arms 0 in. the latter-named yoke being shorter than those of the upper yoke, this variation of arm-lengths affording greater facilities for engaging them with the lips of the base-plates after the papers or pamphlets have been secured to the yokes, for the ends of the longer arms are first inserted under the lips of one plate, and then the ends of the shorter arms are engaged in the same manner with the other plate. The yoke is so bent when made as to cause the arms 0 to extend from the curved bar (I in diverging lines, and the eX- tremities of the arms are bent inward, as shown, to facilitate their introduction under said lips and to form a curved part 0, which serves to prevent the accidental separation of yoke and plate. By causing the arms 0 to stand in diverging lines when not engaged with the base-plate 4 they require to be sprung toward each other when connect-ed to said plate, and thereby the yokes are held to the plate by frictional engagement as well as by the aid of the curved portions 0 thereof.

For many purposes a single yoke and baseplate may serve to secure papers together; but for attaching pamphlets, papers, or sheet music within a cover or covers, two or more of the binder devices are used.

To attach the binder-yoke to pamphlets, &c., a suitable perforation x is made, and one end of the yoke being passed therethrough the paper is easily carried to its place on the curved bar d.

In practice it is preferable not to put as many papers on said curved bar as it can contain, but to leave room enough thereon for a certain freedom of movement of the papers when they are turned over for examination, and in such case the books orpapers will lie quite fiat against the inside of either cover when the latter is opened.

hat Iclaim as my invention is- 1. A temporary binder consisting of a base having opposing turned-over lips at its sides, whereby grooves are formed, and a binderyoke consisting of an intermediate archshaped portion and the spring-arms disposed in a plane at an angle to that of said intermediate portion and adapted to have a sliding engagement With the said groove-forming lips, substantially as and for the purposes described.

2. A temporary binder consisting of a baseplate having opposing turned-over lips at its sides, whereby grooves are formed, and a binder-yoke consisting of an intermediate arch-shaped portion and the spring-arms disposed in a plane at an angle to that of said intermediate portion and provided with the curved portions 0 near their extremities, and said arms adapted to have a sliding engagement with said groove-forming lips, substan tially as-and for the purpose described.
